Step-by-step explanation:
Domains of Development
Developmental psychologists study human growth and change throughout the lifespan by focusing on three developmental domains: physical, cognitive, and psychosocial development. The domain involved with acquiring problem-solving skills and learning new information is cognitive development.
Cognitive development encompasses learning, attention, memory, language, thinking, reasoning, and creativity. This domain is critical in understanding how children and adults take in information, make sense of the world, and apply their knowledge to solve problems.
It differs from physical development, which relates to changes in the body and brain, and psychosocial development, which concerns emotions, personality, and social relationships.
Cognitive development theories, such as those proposed by Piaget, focus on how thinking and reasoning evolve from childhood through adolescence and into adulthood. For instance, during adolescence, processing speed and efficiency tend to increase, leading to more complex thinking abilities and the development of abstract thought. The correct option is 2) Cognitive development
